How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.

    The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.

    The toothbrush will be able to teach you to brush right (don't forget the insides of the teeth!) and make sure you're brushing long enough. “It's kind of like having a doctor actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.

    The toothbrush will also be able to talk to other applications(应用) on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters(怪物) among your teeth. “We try to make it smart but also fun,” Serval says.

    Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.

    The company says the Kolibree will go on sale this summer, for $99 to $199, depending on features. The U.S. is the first target market.

    Serval says that one day, it'll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.

    We arrived at the hospital to find Dad was very weak, but his smile was as sure as ever. It was another attack of pneumonia(肺炎). My husband and I stayed with him for the weekend but had to return to our jobs on Monday. Local relatives would help Dad get home from the hospital and look after him. But I longed to be able to let him know that we cared too, even when we weren't with him.

    Then I remember a family tradition when our children were small. When leaving their grandparents' home after a visit, each child would write a note to their grandparents. They hid notes in the cereal(麦片), under a hairbrush, next to the phone or even in the microwave oven. For days, their parents would smile as they discovered these signs of our love.

    So as I tidied Dad's kitchen and made up a bed for him downstairs in the living room, I wrote some notes. Some were practical, "Dad, I put the food in the fridge so it wouldn't spoil." Some expressed my love, "Dad I hope you will sleep well in your new bed." Most notes were downstairs where he would stay for several weeks until he recovered strength, but one note I hid upstairs under his pillow, "Dad, if you have found this one, you must be feeling better. We are so glad. "

    Just like his medicine strengthened him physically, these "emotional vitamins" would improve his spiritual health. Several weeks later, in one of our regular phone calls, I asked Dad how he was doing. He said, "Pretty good. I just found your note under my pillow upstairs!"

    Google's new camera, called Clips, is a small, smart device. It comes with a case that has a clip (夹子)，but it's not designed to be worn on your clothing. Most interestingly, it uses artificial intelligence to take photography out of your hands so it can capture moments on its own.

    This roughly 2-inch by 2-inch camera, with a three-hour battery life and Gorilla Glass for toughness, is intended for candid moments, like when a child does something cute that may happen too quickly for you to pull out your smartphone.

On board the Clips device, it uses machine learning algorithms (计算程序) to help capture scenes. Those algorithms include face recognition. “Once it learns that there's a face you see frequently, it'll try to get nice photos of those faces,” said Juston Payne, the device's product manager. And they also want it to recognize facial expressions, which involved “training it to know what happiness looks like”. The Google team also trained it to recognize what not to shoot — like when a child's hand is over the lens, or if it is tossed in a dark purse.

    The only way to see the images is by connecting the camera with your phone, as it has no screen for viewing or editing.

    Were people concerned it could seem strange? Yes, Payne admitted. But they said they addressed that by making it obvious what it is. A green light on the front signals that it is on. Besides, unlike a camera meant to monitor your home, it is not connected to the Internet.

    “This product is only possible because of the way that silicon has advanced” Payne said, noting that it was only in the past year or so that they could squeeze the technology down into a device this size. Going forward, we're likely to get more assistance from the artificial intelligence packed into our apps and gadgets.

    Everywhere I look outside my home I see people busy on their high-tech devices, while driving, walking, shopping, even sitting in toilets. When connected electronically, they are away from physical reality.

    People have been influenced to become technology addicted. One survey reported that “addicted” was the word most commonly used by people to describe their relationship to iPad and similar devices. One study found that people had a harder time resisting the allure of social media than they did for sleep, cigarettes and alcohol.

    The main goal of technology companies is to get people to spend more money and time on their products, not to actually improve our quality of life. They have successfully created a cultural disease. Consumers willingly give up their freedom, money and time to catch up on the latest information, to keep pace with their peers or to appear modern.

    I see people trapped in a pathological(病态的) relationship with time-sucking technology, where they serve technology more than technology serves them. I call this technology servitude. I am referring to a loss of personal freedom and independence because of uncontrolled consumption of many kinds of devices that eat up time and money.

    What is a healthy use of technology devices? That is the vital question. Who is really in charge of my life? That is what people need to ask themselves if we are to have any chance of breaking up false beliefs about their use of technology. When we can live happily without using so much technology for a day or a week, then we can regain control and personal freedom, become the master of technology and discover what there is to enjoy in life free of technology. Mae West is famous for proclaiming the wisdom that “too much of a good thing is wonderful.” But it's time to discover that it does not work for technology.

    Richard Fernandez, an executive coach at Google acknowledged that “we can be swept away by our technologies.” To break the grand digital connection people must consider how life long ago could be fantastic without today's overused technology.

    For most of her life, Suanne Laqueur's passion for storytelling was shown on the dance floor.

    Although Laqueur began writing at a young age, dancing always took center stage. She majored in dance and theater at Alfred University and taught at her mother's dance studio in Croton-on-Hudson, New York, for years. But when her mother was ready to retire and an opportunity opened for Laqueur to take over the studio, she realized she had no interest in taking on the business side of her art: “Owning a studio is a lot of work—financially, logistically. I love the teaching, the choreographing(编舞), the staging, but I didn't want to own it.”

    Yet Laqueur's disinterest in running the studio changed when she became a self-published author. In the fall of 2013, she decided to pursue Self-publishing as a way of sharing her first completed novel with friends and family. During the process, she realized that following her true passion—telling stories through writing—made the business of the art worthwhile, and owning that business meant she could direct her writing career however she chose.

    Starting with her second self-published novel, she began investing more time in marketing and building her audience. Her investment paid off. Since 2014, Laqueur, now 49, has self-published six novels, which collectively have hundreds of ratings and reviews on Good reads. Her 2016 novel An Exaltation of Larks stole the show at the 25th Annual Writer's Digest Self-Published Book Awards, topping more than 2,300 entries to win the grand prize.

    “You have to write the most truthful story to you, and I think self-publishing allows that freedom,' she says. “If you work with traditional publishing, it's more about what's marketable, There are trade-offs, which everyone will tell you, but by self-publishing I have control of the book, I have control of the story, and I'm cool with that.”
